Is Forza Motorsport 3 1player or more

Forza 3 has 1 player online, or 2 player split screen. In split screen you can have computer controlled cars racing too. This is one reason I like Forza games, as games like NFS Shift, Grid, Pure, Dirt, and Dirt 2 don't have split screen. Trust me, I have Forza 3. =D
